VPNs – What Is It, and Do I Need One?

In this episode of Geek to English, we demystify Virtual Private Networks, or VPNs. We break down what they are, how they work, and why people use them for privacy, security, and access. You’ll also hear about popular services like NordVPN, Proton VPN, and Surfshark VPN, plus some real-world risks like unsecured public Wi-Fi and “juice jacking” USB ports.

We wrap up with a balanced look at whether you really need a VPN and compare digital vigilance to the everyday habit of locking your car doors—even when you’re just sitting inside.
